Disconnect your battery for five minutes. That will reset your computer. When the problem happens again, take your car to Auto Zone or Advanced Auto. They have a code reader and will tell you what the problem is. This is a free service. Good luck

How can i fix my locked up engine in my 1987 crown victoria? i had oil in it and to my knowledge my starter was good. what route should i take next?


Try taking out the spark plugs put motor oil in all cylinders and let it sit for a day or 2 fully charge the batterry for the 2 days on (2 amp if possible) try it again a few times if it still won't free up use a socket on a breaker bar on the harmonic balancer bolt and try to turn it manually...Good Luck
